Surgical morcellator

Abstract

Embodiments described a shield for a surgical morcellator. Specifically, embodiments disclose a denticulate shield for the distal tip of a surgical morcellator with notches, wherein the notches are configured to catch loose morcellated tissue and prevent the loose morcellated tissue from being falling or remaining into the patient.

What is claimed is: 
     
       1. A surgical device comprising:
 (1) an inner tube having a first proximal open end with a first proximal diameter, and a first distal open end with a first distal diameter; 
 wherein the inner tube includes a rotatable cutting edge on the first distal open end having an axis of rotation; 
 (2) an outer tube having a second proximal end with a second proximal diameter, and a second distal open end with a second distal diameter; 
 wherein the second distal diameter is greater than the first distal diameter; 
 wherein at least a portion of the outer tube is configured to extend around the inner tube; and 
 (3) a denticulate shield that does not rotate having a third proximal end, a third distal end, and a body configured to be radially offset from the axis of rotation of the inner tube, the body defining at least one first notch, the first notch configured to face tangential to rotation of the cutting edge; 
 wherein the body includes a first lateral side edge and wherein the first notch is defined at least partially by at least one edge extending inward from the first lateral side edge; 
 a tenaculum configured to extend through and distally out the first distal open end of the inner tube and the third distal end. 
 
     
     
       2. The device of  claim 1 , wherein the at least one inward edge includes a pair of converging inward edges forming an angle of convergence. 
     
     
       3. The device of  claim 2 , wherein the converging edges form a V, W, or Z shape. 
     
     
       4. The device of  claim 2 , wherein the denticulate shield has a first position wherein the denticulate shield's third distal end is proximal to the cutting edge; a second position wherein the denticulate shield's third distal end is distal to the cutting edge a portion of a length of denticulate shield; and a third position wherein the denticulate shield's third distal end is distal to the cutting edge at least the length of the s denticulate shield. 
     
     
       5. The device of  claim 4 , wherein the denticulate shield is able to move between the first position and third position. 
     
     
       6. The device of  claim 2 , wherein an angle of convergence is less than 130 degrees. 
     
     
       7. The device of  claim 1 , wherein the first notch is a V, W, Z, or U shape. 
     
     
       8. The device of  claim 1 , wherein the first lateral side includes a plurality of notches. 
     
     
       9. The device of  claim 1 , wherein the at least one inward edge includes a pair of non-converging parallel edges. 
     
     
       10. The device of  claim 1 , wherein the first notch is 2 mm to 7 mm deep and 2 mm to 7 mm wide.
